Quarry Dust: The Potential of By-Product Waste as Sulfate Attack Resistance in Cement Composites
Get PDFIn this study, the durability of cement composites at 0 wt.%, 12.5 wt.%, and 17.5 wt.% of the addition of quarry dust was investigated against sulfate attack at 1,2,3,4,8,13 and 15 weeks. The specimens of cement composites were immersed in sodium sulfate solution and evaluated for length change and salt deposition. Cement composites with the addition of 12.5 wt.% of quarry dust were found to possess the best sulfate attack resistance. The sodium sulfate solution was found not to affect the original length of the cement composites at all percentages of quarry dust. A visual examination revealed that the cement composites without the addition of quarry dust showed the existence of salt deposition compared to 12.5 wt.% and 17.5 wt.%. The quarry dust consumption presented the cement composites\u27 durability improvement due to sulfate attack. The silica content and filing effect of quarry dust chemically react with the calcium hydroxide released by ordinary Portland cement to form durable cement composites
Potential of Fly Larva and Anchovy Process Waste Powder as Protein Source in Tilapia Fish Pellet
Get PDFFeeding is one of the most crucial aspects of fish culture activities. The rise of pellet prices due to the lack of raw material has led the farmers to shift to alternative protein sources. This research aims to study the potential of fly larva flour and anchovy process waste as a cheap alternative protein source for tilapia farming. Tilapia fishes with average length were divided into four different treatments. T1 is a control treatment (fish pellet) while T2, T3 and T4 contain a mixture of fly larva powder and anchovy process waste powder (45%, 50% and 55% mixture of fly larva flour and anchovy head flour). Fish growth rate, survival rate and water quality were recorded weekly throughout the study period. Data analysis shows that there are no significant differences amongst each treatment. This study indicates that fish supplied with a mixture of fly larva powder and anchovy process waste powder shared the same growth rate as the fish supplied with commercial pellets

Industry Perception on the Implementation of Work-Based Learning (WBL) in Politeknik Ibrahim Sultan
Get PDFWork-Based Learning (WBL) is a type of learning that integrates theoretical and practical learning in the context of real-life situations. In September 2013, Politeknik Ibrahim Sultan became one of Malaysia\u27s first public higher learning institutions to use the Work-Based Learning technique in both teaching and learning in the tourism and hospitality management discipline at the undergraduate level. The objective of this study is to evaluate the feedback and perception of industry on the implementation of WBL. This study uses a mixed method of qualitative and quantitative approaches. Data collection was based on the students’ performance appraisal form, semi-structured interviews during lecturer visits and meetings between polytechnic management and the companies involved. The main informants are companies who have gone through the WBL procedure. The data was analysed by employing a matrix of categories and categorising the evidence. There are five indicators for this study, which are the competencies of students, student discipline, competencies of industrial supervisors, communication between institution and industry, and the effectiveness of the WBL as a teaching and learning approach. According to the findings, the Work-based Learning technique is incredibly efficient in supporting students in enhancing their skills and knowledge while also raising their chances of finding work. However, the study identifies a number of concerns and obstacles that must be addressed, including information coordination, continuous cooperation, and the lack of teaching and learning competency among industrial supervisors. The study shows that supervisors should be academically prepared and have a thorough awareness of their role in implementing WBL. Besides, in future, it will be important for PIS to conduct a study to evaluate the feedback from industry at the end of the WBL session. This is to enable corrective action to be taken as soon as possible for improvement for the next WBL session
